c. M. WOOLLEY AIR CIRCULATING ATTACHMENT FOR HEATING RADI Filed Sept. 26, 1935 ATORS Patented Mar. 1939 HEATING RADIATORS Clarence M. Woolley, New York, N. Y., assignor to American Radiator Company, New York, N. Y., a corporation of New Jersey Application September 3 Claims.

My present invention relates to thermal enhancing attachment for thermal radiators.

More particularly, my present invention is directed to an attachment constructed and arranged to be associated with a thermal radiator, heating or cooling, which maybe of any standard type, the

attachment including one or more motor-fan units, a casing for housing and supporting the same, the casing being provided with air ingress openings, the stated. assembly when associated with the radiator being positioned lowerlyof the thermal exchange surfaces of the radiator.

In preferred embodiments of my invention, each motor fan unit is unitarily assembled with the easthe casing, and means are provided forstationarily installing the embodiment relative to the radiator. I Advantageously, the air ingress openings are located in predetermined relation to the radiator, i. e. to the usual respective sections of the radiator, the remainder of the sides of the casing being imperforate, whereby during the stage of fan operation, the projected air-transverse predetermined paths of flow over the thermal i.' e. heating or cooling, exchange surfaces ofthe radiator.

Utilization of my invention, as appears, results in enhancing the output of thermal units delivered by any radiator of any given total heating radiating surface, and additionally increases the circulation, i. e. re-circulation, of the air of the room or other space served by the radiator.

Further features and objects of the invention will be more vfully understood from the following detail description and the accompanying drawing, in which Fig. 1 ma side elevation, partly broken away for the sake of clarity, of a preferred type of embodiment of my invention.

Fig. 2 is a sectional view on line 2-2 of Fig. 1. Referring to the drawing, at In is illustrated any suitable type of thermal radiator, heating or cooling, the proper thermal medium being supplied to the radiator. The specific radiator iithe sections being individually designated la and the spacings between the sections being designated lilb; a supply pipe is indicated at H having a conventional shut-off valve I2; the 'valve it indicates any suitable steam trap, connected. in the return pipe I 4.

The embodiment of my invention illustrated in he drawing comprises a casing, the front side rtion |5a being provided with air ingress openn'gs l6. In the particular type of embodiment iling and most preferably resiliently supported by lustrated in Figs. 1 and 2 is'of the sectional type,

lustrated in the drawing, the material of the remainder of the sides of the casing, i. e. the op I posite ends l5b, I50, are imperforate. In the embodiment illustrated in the drawing, there is no rear side of the casing, but which may be supplied if desired Air ingress openings may be supplied in the opposite ends I51), 150, if desired.

Housed within such casingjare one or more motor-fan units, the specific embodiment illustrated in the drawing being equipped with two motor-fan units, the motorbeing designated Ill and the fan l8.

Each motor-fan unit is unitarily assembled with the casing, instanced in the illustrated embodi ment by mounting each motor-fan unit upon a plate l9, suitably secured to the casing, as, see

Fig. 2, by attachment to a bracket 20, the fixed end of which is secured to or integral with the material of the front side l5a of the casing.

Desirably, the motor I! is of the electrical type, and in precaution of possible'leakage of electrical current, insulation, see 2|, is interposed between 1 the plate I!) and the bracket or extension 20.

Preferably, as shown, each motor-fan unit is resiliently supported, as by positioning the supporting plate I!) the room or other space served by the radiator III,

in spaced relation to the floor 22 of the opposing ends of the plate I9, see l9a, being supported in spaced relation to the floor 22 by angled extensions or the likeserving as feet. The supporting plate IS in effect provides floor means for the casing, and is secured to the casing as by means of the bracket extending upwardly within the casing andengaging, at the bottom, the footing provided by the angled inward extension of the bottom of front wall l5a, note Fig. 2.'

To safeguard against incidental displacement of the casing and the therein housed parts, particularly of the type of casing having a rear open side, I recommend a rod 23 or equivalent, passing from one end,|5b to the opposing end I50, and suitably attached to the same, as by means of nuts 24 or equivalent. 1

v In Figs. 1 and 2, the radiator is shown elevated by pedestal-like members 25, which may be necessary or desirable to provide proper clearance under the radiator for the positioning of my attachment.

As appears from the embodiment of my invention illustrated in Figs. 1 and 2, the casing has an outer contour conforming to the configuration defined by the mutually spaced feet or pedestallike members serving to support the thermal exchange surfaced elements of the radiator per se;

Embodiments of my invention, as now appears, serve to increase the rise of temperature of the air of the room or other space served by any given radiator, by reason of the air projected by the 5 provide for one or more intermediate speeds, as

well as full'speed and off positions.

For varied speeds of rotation of the one or more fans, the path of flow of the projected air in thermal exchange relation with the thermal surfaces of the radiator is. extended more upwardly, as

well as increasing the mean rate of re-circulation of the air of the room or other space served by the radiator.

Whereas I have described my invention by ref erence to specific forms thereof it will be under-l stood that many changes and modifications may be made without departing from the spirit of the invention.

I claim:

1. ,An as article of manufacture, a device for effecting circulation of air, said device comprising a portable assembly including a casing having panel walls provided with ports and an open top; footing secured to said casing and extending inwardly thereof, said footing being adapted to rest directly on a supporting surface; supporting means secured to the inner extension of said footing and extending upwardly within said casing; floor means secured to the upper part of said supporting means and extending substantially horizontally above the level oi said footing; foot means remote from said footing for supporting said floor means directly on said supporting surface;

on said floor means for drawing air through the andone or more motor-fan units mounted ports of said panel walls and discharging air through said open top of the casing.

2.-As an article of manufacture, a device for effecting circulation of air, said device comprising a portable assembly includinga substantially rectangular casing having panel walls and an open top, a longitudinal wall of which is ported; footing formed at the bottom of said longitudinal wall and extending inwardly longitudinally thereof, said footing being adapted to rest directly on a supporting surface; supporting means secured to the inner extension of said footing and extending upwardly within said casing; floor means secured to the upper part of said supporting means and extending substantially horizontally above the level of said footing; foot means remote from said footing for supporting said floor means directly on' said supporting surface; and one or more motor-fan units mounted on said floor means for drawing air through the ports of said panel walls and discharging air through said open top of the casing.

3. As an article of manufacture, a device for effecting circulation of air, said device comprising a portable assembly including a substantially rectangular casing having an open top and a front longitudinal wall, end walls extending backwardly from said front wall, and reinforcing means connecting the free ends of said endwalls, said front wall having its bottom bent inwardly to form a footing extending longitudinally of said casing, said footing being adapted to rest directly on a supporting surface; supporting means secured to the inner extension of said footing and extending upwardly within said casing; floor means secured to the upper part of said supporting means and extending substantially horizontally above the level of said footing; foot means remote from said footing for supporting said floor means directly on said supporting surface; and one or more motor-fan units mounted on said floor means for drawing air through the ports of said panel walls and discharging air through said open top of the casing.
